Patient | Age (years) | Sex | Indication for surgery | Histopathology | Duration of follow-up (months) | Clinical outcome |
10 | 43 | Female | Presumed infectious keratitis. | Not performed. | 6 | Graft intact, epithelialised, opacified. |
11 | 47 | Male | Presumed infectious keratitis. | Not performed. | 6 | Graft intact, epithelialised, opacified. |
12 | 65 | Female | Presumed herpetic keratitis. | Acute inflammation and necrosis. | 105 | Graft intact, epithelialised and remained clear. |
13 | 65 | Male | Bacterial keratitis. | Acute inflammatory infiltrate and necrosis. | 5 | Graft intact, epithelialised and opacified. Underwent subsequent optical PK with fresh tissue, which also opacified. |
14 | 48 | Female | Presumed herpetic keratitis. | Acute inflammation and necrosis. | 30 | Graft intact, epithelialised and clear. |
15 | 81 | Female | Presumed herpetic keratitis. | Acute inflammation and necrosis. | 6 | Graft intact, did not epithelialise, developed bacterial ulcer and perforated. Underwent tectonic PK with fresh tissue, then lost to follow-up. |
16 | 51 | Female | Presumed herpetic keratitis with bacterial superinfection. | Acute inflammation and necrosis. | 100 | Graft intact, did not epithelialise, developed fungal keratitis. Underwent tectonic PK which failed, and eventually conjunctival flap performed. |
17 | 80 | Female | Presumed herpetic keratitis with fungal superinfection. | Acute inflammation and necrosis, fungal elements. | 91 | Graft intact, did not epithelialise and cornea melted. Underwent tectonic PK and KPro—both failed, and eye eventually became phthisical. |
18 | 44 | Female | Presumed herpetic keratitis with bacterial superinfection. | Acute inflammation and necrosis, Gram-positive cocci. | 55 | Graft intact, epithelialised and clear, but eventually developed endophthalmitis. Underwent subsequent tectonic PK which failed. |
KPro, Boston type 1 keratoprosthesis; PK, penetrating keratoplasty.
